You find one good book – you might want to find more! Here are some tips on how to find more books like the one you just found.
Use iDiscover to search for words in the title of the book you're finding useful
Try looking next to it on the shelf where you found it. Many libraries use a classification system that organises the books by subject – so books on the same topic will be on either side of it on the shelf
Use university reading lists issued by your department to find books on a similar subject
